Smartibot - BTN1 and BTN2 access

I have updated my Smartibot to version 2.04 and last night started to work through some of the examples in the documentation.

First one I tried was button presses

setWatch(function(e) {
  if (e.state) print("Button pressed");
  else print("Button released");
}, BTN, {repeat:true});

When I download this "Button pressed" is printed only when Button A on the smartibot is pressed, nothing when released and nothing for Button B.

So looking at some examples I added

var smarti = require("Smartibot");

to the top and this made no difference.

I then tried the "block" coding and used the set watch construct.
First block was BTN1 rising and inside I change the colours of the leds. This was then duplicated for BTN1 falling, then I duplicated both for BTN2.

Downloaded and it worked.
Tried to change the code but somehow deleted everything, when I started again BTN2 was not available.

This morning I started to create the post, initially the same problem , no BTN2.
Tried refreshing the browser still did not work.
So I downloaded the raw javascript to prove that did not detect BTNB , it did not.

Then went back to "block" mode and BTN2 is available.

I am using Chrome on a mac and I am new to java script.

My questions are:

1. what is wrong with the raw javascript code I downloaded ?
   
2. have I found a bug with the block code ?
   
   

PS should I have tagged this post or posted elsewhere so it is obvious it is a smartibot issue I am having.
